Description

Electric test operating lever

technical field

The utility model relates to an electric test equipment, in particular to an electric test operating rod.

Background technique

When the power distribution line is stopped and transmitted, the pointer of the circuit breaker is often encountered, but it is impossible to accurately judge whether the inside of the circuit breaker is really disconnected only through the pointer movement. At this time, it is necessary to conduct an electrical test on the load side of the circuit breaker before the disconnector can be pulled. Since the positions of the load side of each circuit breaker are different, it is necessary to use electroscopes with contacts in different directions to carry out electrical inspection work on them. Therefore, operators need to replace the electroscopes repeatedly. In order to ensure safety, the staff usually fix the electroscopes in one place. On the insulating operating rod, but because there is no professional tool, the staff can only be bound on the insulating operating rod by wire or cloth strips and other electroscopes, which not only wastes time, but also has poor fixing effect.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Fig. 1 and Fig. 2, the utility model discloses an electric inspection operating rod, which is used for electric detection of a circuit breaker in a line. The electric inspection operating rod includes an insulating tube 1 and a detection device. The detection device includes an electroscope 2 installed at one end of the insulating tube 1 and a detection joint 4 that is covered outside the electroscope 2 and is detachably connected with the insulating tube 1, that is, the electroscope 2 is located between the detection joint 4 and the insulating tube. In the space surrounded by 1, the electroscope 2 is electrically connected with the detection joint 4.

Specifically, as shown in Figure 1 and Figure 2, one end of the insulating tube 1 is provided with a connector 8 for connecting with the detection joint 4, and one end of the electroscope 2 is provided with a positioning rod 3 for penetrating into the insulating tube 1, When the positioning rod 3 penetrates into the insulating tube 1 , the electroscope 2 abuts against the connector 8 , that is, resists the electroscope 2 to prevent it from falling into the insulating tube 1 . The detection connector 4 is a metal cylinder with one end open and the other end closed. The open end is provided with an internal thread, and the connector 8 is provided with an external thread for internal thread connection, that is, the detection connector 4 and the connector 8 are threaded. connect.

Further, the electroscope 2 in the present embodiment is a short cylindrical shape (certainly also can be other shapes), and an indicator light and a switch 10 are arranged on its outer peripheral surface, and an end of the electroscope 2 facing the detection joint 4 is provided with a The electrical contact 7 electrically connected to the connector 4 has a non-unique structure. The electrical contact 7 in this embodiment is a spring. When the detection connector 4 is covered outside the electroscope 2 and connected to the insulating tube 1, the closed end The inner wall abuts against the spring (at this time, the spring is compressed by the detection joint 4 to ensure stable contact between the spring and the detection joint 4). The corresponding indicator lights and switches 10 on the detection connector 4 are respectively provided with operation holes 6 that match the shape of the indicator lights or switches 10, so that the indicator lights and switches 10 are exposed for easy observation and operation.
